Comparative evaluation of the bonding of glass-ionomer cement modification to dental composite established by dental adhesives.

Abstract

Objective: To evaluate the influence of the application of various adhesives on the strength of the bonding established amongst resin-modified glass-ionomer cement (RMGIC) and resin composite restoration (RBC).Materials and method: Twenty discs were made-up with (RMGIC) and divided into four groups (n = 5) based on the adhesive resin system applied. Cylinders of resin composite were bonded to the RMGI discs utilizing different adhesive resin systems in the first three groups. While the fourth group was used as a control receiving no adhesive resin treatment. Microshear bond strength was measured and the data was registered with computer software in MPa. Results:The results revealed that applying different adhesive resin systems statistically significantly increased the bond strength between the tested materials. Conclusion:Microshear bond strength of (RMGIC) to resin composite improved considerably using different adhesive resin systems. The outcomes vary depending upon the type of adhesive resin system utilized.
